2‐Substituted 3‐dimethylamino‐ and ‐3‐cyanopropenoates in the synthesis of heterocyclic systems
Journal ArticleDOI
Parallel synthesis of 3-amino-4H-quinolizin-4-ones, fused 3-amino-4H-pyrimidin-4-ones, and fused 3-amino-2H-pyran-2-ones.
TL;DR: The solution-phase synthesis afforded, in most cases, analytically pure products in high yields, whereas the solid-phase approach gave products in poor yields and in low purity.

X-ray scattering factors computed from numerical Hartree–Fock wave functions
D. T. Cromer,J. B. Mann +1 more
TL;DR: In this paper, the Hartree-Fock wave function was used to compute X-ray scattering factors for neutral atoms from He to Lw and for most of the chemically significant ions through Lu3+ through Lu 3+.

Relativistic Calculation of Anomalous Scattering Factors for X Rays
Don T. Cromer,David A. Liberman +1 more
TL;DR: In this paper, relativistic calculations of the photoelectric cross section have been made and the integral for the principal contribution to Δf′ has been evaluated numerically without approximation to the form of the cross section-vs-energy curve, as has been done in previous calculations.

Coherent X‐Ray Scattering for the Hydrogen Atom in the Hydrogen Molecule
TL;DR: In this paper, the x-ray form factors for a bonded hydrogen in the hydrogen molecule have been calculated for a spherical approximation to the bonded atom, and the corresponding complex scattering factors have also been calculated.

A general theory of X‐ray diffraction in crystals
TL;DR: In this paper, Werner pointed out what he believed to be an error in his paper concerning the physics of diffraction in perfect crystals, and called to the attention of X-ray crystallographers certain aspects of two papers (Werner & Arrott, 1965; Werner, King & Kendrick, 1966) on neutron diffraction which have a direct bearing on the extinction problem.

The synthesis and transformations of ethyl (Z)-2-[2,2-bis(ethoxycarbonyl)vinyl]amino-3-dimethylaminopropenoate, a new reagent in the synthesis of heterocyclic compounds
TL;DR: In this paper, a new reagent for the synthesis of hetero-cyclic β-amino-α,β-dehydro amino acid derivatives and some fused heterocyclic systems was obtained from N-2,2-bis(ethoxycarbonyl)vinyl glycinate and N-N-dimethyl-formamide dimethyl acetal.
